| Living room, bedroom, dining room, or hallway | Dry indoor conditions with no expected water contact | IP20 | Protection against solid objects larger than 12.5 mm; no water protection | Suitable for ordinary dry interiors when the fitting is installed away from sinks, showers, and other water sources. |
| Kitchen ceiling or wall away from the sink | Occasional steam, grease, and light splashes | IP44 | Protection against solid objects larger than 1 mm and splashing water from any direction | Choose a sealed fitting where steam or splash exposure is likely. Keep the fitting outside the area where direct water spray can reach it. |
| Bathroom outside the defined zones | Humidity and occasional condensation | IP44 | Protection against objects larger than 1 mm and water splashes | Use a light specifically approved for bathroom use and follow the required clearance distances and wiring rules in local electrical regulations. |
| Bathroom Zone 0: inside a bath or shower basin | Continuous or temporary immersion in water | IPX7 or higher | The second digit 7 indicates protection against temporary immersion in water | Only use equipment specifically permitted for Zone 0. Because “X” does not state solid-particle protection, check the complete product marking and local code requirements. |
| Bathroom Zone 1: directly above a bath or shower | Water jets, spray, steam, and high humidity | IPX4 or higher | The second digit 4 indicates protection against splashing water from any direction | Use IPX5 where water jets may occur or where local regulations require it. Confirm the fitting is rated for the applicable bathroom zone. |
| Bathroom Zone 2: area beside a bath or shower | Occasional splashes and condensation | IPX4 or higher | Protection against splashing water from any direction | Install only within the permitted dimensions for Zone 2 and use a suitable residual-current protection device where required by local regulations. |
| Covered porch, balcony, or sheltered entryway | Humidity, wind-driven rain, and occasional splashes | IP44 | Protection against objects larger than 1 mm and splashing water | Use a higher rating if rain can reach the fitting directly. Ensure the brass finish and all fasteners are suitable for the outdoor environment. |
| Outdoor wall or ceiling exposed to rain | Rain, dust, and water projected by wind or cleaning | IP65 | Dust-tight and protected against water jets from any direction | Use a fully sealed outdoor fitting with suitable cable entries and gaskets. Prevent water from collecting around the mounting point. |
| Garden, patio, or area subject to temporary flooding | Heavy rain, hose spray, and possible short-term immersion | IP67 | Dust-tight and protected against temporary immersion in water | IP67 does not automatically mean protection against high-pressure water jets. Check whether the fitting also carries a suitable jet-resistance rating for the location. |
| Coastal or high-salt outdoor environment | Salt spray, moisture, wind, and accelerated corrosion | IP65 minimum | Dust-tight and protected against water jets | IP rating covers ingress, not corrosion resistance. Select marine-suitable materials or finishes, inspect regularly, and use corrosion-resistant fixings. |
